I've had Nickel for about eight months, and Kona since February. I learned most of what I know about Angoras from a very reputable Angora breeder. I had started reading on the Ravelry Angora forums, and then found a listing posted by a woman, and started talking to her about showing rabbits. She invited me to come to a rabbit show and learn more. While I was there I learned about the five Angora breeds and pros and cons of each, care, a little bit about color genetics, etc. I also got to handle a ton of cute bunnies and helped them move them back and forth. It's a huge exciting world. I still may consider showing rabbits someday when I have the funds to pay for all the cages and rabbits to start up with. There's also a lot of info on Angora web sites!
For angoras, low maintenance coats are the best! If you want a wooler/pet you get to pay a lot less for your rabbit! Breeders always have extra due to the prolificy of rabbits, and they'll sell their pet quality cheaper. Make sure you get a breeder that also is a spinner. They know what to look for in a nice spinning coat. French and Satins usually have very easy care coats. French produce more but Satin produce finer. Kona's is like silk, fine and strong. Germans and Giants produce the most, but they are very expensive even for pet quality. Getting a rabbit from a good breeder means that they will be friendly right off the bat, which makes grooming a breeze and social interactions delightful. Kona's a love bug.
Unless your bunny is inside the house, get two. I had Nickel by herself in the shed for a few months, and she was so shy. Now that she's had Kona for a neighbor for a couple months, she's downright friendly, asking for petting when I feed her. You do need separate cages unless you get two siblings raised together, though. Apparently you can have rabbits get along after a long drawn out socialization process, but I've yet to have time to do that.
Besides that, feed your bunny good quality pellets, I use 16% protein, and free feed hay to help move the wool along their intestines and avoid wool block. You can also give them veggie treats eventually, mine all love carrots! Get a cage plenty big enough, you can even potty train bunnies. (I haven't read this whole thread, people probably talk about it). Our inside bunny the holland lop was not good at potty training, it took her a few months and she still leaves dingleberries on the carpet eventually. But we did get her to use a littler box inside the cage. You can't have an angora use an open litter box because of their fur, but you can use a litter box with a wire top on it.
Angoras are bred to be sweet and easy to handle for grooming. They are soft and adorable! I am hoping to sell some of the fiber from mine when I get enough time to take some photos and do some listings for my Etsy shop.
